Subject: scsi: lpfc: Fix nvme target failure after 2nd adapter reset
Patch-mainline: v4.14-rc1
Git-commit: a145fda3816ed516af5c589ef296a50897c42ef9
References: bsc#1050239,FATE#322918
The nonrecovery occurred because the lpfc nvme initiator function did
not reestablish its localport creation with the nvme host transport in
lpfc_oneline. Because of that, an NVME rport binding could not take
place.
Corrected by recreating the localport in the adapter reset recovery
routine.
